We're Australia and New Zealand's largest Mathcad distributor.
Calculations are the heart of engineering information yet too many companies fail to properly solve, document, and share their engineering calculations. They lose invaluable intellectual property with every new project, resignation or retirement. Mathcad is the first and only engineering calculation solution that simultaneously performs and documents engineering calculations while dramatically reducing the risk of costly errors.

Other features of Mathcad Prime

Global Definitions The Global Definition operator allows you to define and evaluate a variable anywhere in your worksheet without having to worry about calculation order. This makes both worksheet management and documentation presentation easier – constants and parameters can be defined as ‘true’ throughout your worksheet and can be placed close to the end result of the calculation to support ‘what if’ analyses, as well as for clear and concise presentation of your work.

Math in Text – Mathcad Prime 3.1 allows math and text to be seamlessly integrated to provide a natural text flow that increases the readability of your worksheet definitions, design notes and explanatory text. Live math can be inserted, pasted and moved anywhere within text to augment worksheet presentation with content that will update on upstream changes in calculation. By enabling math within text, Mathcad Prime 3.1 allows you much greater scope with your worksheet presentation.

Templates – Save you time and effort with templates by providing the ability to define and organize desired content in such a way as to allow simple and structured re-use in creating new worksheets. Anything you can do with a worksheet, be it adding calculation content or changing documentation formatting, can be saved in a template. Documents can be standardized, IP can be captured and your desired format can be reused as often as you need.

Custom Functions – Hundreds of built-in functions that cover a multitude of engineering disciplines. With Custom Functions you can now write and integrate your own functions, customizing your working environment to suit whatever engineering needs you have.

Advanced Numerics – Improved calculation capabilities. Building on the improvements seen in Prime 2.0 (native 64-bit support, linear algebra, signal processing, just to name a few), Prime 3.10 adds new matrix decompositions functions: LU, QR and Cholesky. These functions replace the old lu, qr and cholesky counterparts. The new functions are up to 100 times faster, provide extended capability (such as pivoting, and complex number support) and return the result in easier to work with format.

Excel Component – You’ve got a large data set in Excel that’s critical to your design. But you don’t want to use that tool for your calculations. Mathcad‘s Excel component was designed for exactly that problem. PTC Mathcad is the industry standard for engineering calculations because it saves you time, reduces risk and integrates with many tools you may already be using.

Symbolics – Like many features in the software, it automates a task that is cumbersome, time-consuming and risky if done manually. With symbolics, you can set up the right form of a formula before plugging in the numbers. Routine updates to downstream computations are managed automatically, so your documents remain up to date even as your formulas change.

Solving Capabilities – Its advanced features, like solve blocks, make it a powerful engineering tool. The solve block capability lets you quickly and easily solve systems of linear, non-linear, and differential equations. It lets you solve any number of equations and unknown variables – you can analyze a wide variety of problems according to a set of constraints that you specify.

Advanced Plotting – 3-D plotting in PTC Mathcad is simple to use, and incredibly effective because it lets you work faster with fewer mistakes. Create a plot with the click of a button; both surface and curved based plots automatically rescale when you make adjustments to the data. Any engineer can easily manipulate, analyze and visualize complex data right in the worksheet.

Mathcad 15 Features

Highlights of the enhancements in Mathcad 15.0 include:

Design of Experiments (DoE) – Over 25 new functions to reduce the time and expense of conducting experiments thru DoE by understanding the variable interactions that will influence the experiment. DoE helps identify critical factors and optimal settings for complex processes. It provides templates for a fewer number of experiments which are indispensable when having multiple variables and levels.

Integration to Knovel Math content – Quickly access the full list of Knovel’s fully documented Mathcad worksheets from Roark’s and Hick’s reference works reducing the time it takes to solve complex math problems.

Integration with Kornucopia software – Kornucopia by Bodie Technology, is designed to reduce time and effort spent on analysis by providing functions and templates using Mathcad-based documented workflows, that improves interpretations and value of experimental data and simulation results

Integration to Truenumbers – Truenumbers by True Engineering Technology enables the ability to easily communicate values across applications and the organization without loss of quantity or unit integrity. Results and values can be moved outside of Mathcad onto different document types – enabling easy sharing of the data

Support for Microsoft Excel2007 – Leverage the following functions and features with Excel: READEXCEL(), WRITEEXCEL(), READFILE, the data import wizard, and the Excel Add-in

Windows 7 support
